Siegfried

Behold the tractor tank.

The Siegfried is an Imperial Guard light tank first developed during the civil war on Krieg. It was seen as a replacement for the Sentinel, whose locomotive system was too complex and armoring too light for the dangerous conditions on Krieg at the time. Derived from the famous Land Crawler agricultural vehicle, it was armed with a Multi-Laser and replaced the Land Crawler's simple yet sturdy catalytic engine for a more powerful gas turbine one which, despite being fit with considerably more armor, doubled the Siegfried's top speed. To put things into perspective, the Land Crawler is a over glorified Imperial farming tractor, yet the Kriegers still found some use for this vehicle and modified the tractor into a tank.

When Kriegs lovely civil war has ended, the return of Sentinels kind of made the Siegfried redundant, as even if the Siegfried fared better in the trenches of Krieg then the chicken walker, the Sentinel is still a whole lot more agile and faster than the Siegfried, not to mention that the Sentinel can traverse terrain that can make the tractor tank get stuck somewhere as well as the fact that decent anti-tank weapons such as Lascannons can turn the Siegfried inside out. As much as the Siegfried has improved on the Land Crawler, it was still no Ragnarok. Still the Siegfried still find some use as a mobile reserve and breakthrough tank.
